Brown fused aluminum oxide grinding wheels are a major category of abrasive tools in the process of abrasive machining. A grinding wheel is a porous body made by adding a binder to the abrasive material, followed by pressing, drying, and firing. Due to the differences in abrasive material, binder, and manufacturing process, the characteristics of grinding wheels vary greatly, thus having a significant impact on the processing quality, production efficiency, and cost-effectiveness of abrasive machining. The characteristics of grinding wheels are primarily determined by factors such as abrasive material, particle size, binder, hardness, structure, shape, and size. There are many types of grinding wheels.

abrasive wheels, which can be divided into general abrasive wheels (such as corundum and silicon carbide, etc.) based on the abrasive material used.

Wheels can be categorized by shape into flat grinding wheels, bevel edge grinding wheels, cylinder grinding wheels, cup grinding wheels, disk grinding wheels, etc.; and by binder into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels, and metal grinding wheels, among others. The main characteristic parameters of grinding wheels include abrasive, grain size, hardness, binder, structure number, shape, size, and linear speed, etc.

Since grinding wheels typically operate at high speeds, they should be subjected to a rotation test (to ensure they won't crack at high working speeds) and a static balance test (to prevent machine vibration during operation). After a period of use, the grinding wheel should be dressed to restore its grinding performance and proper geometric shape.
